Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Usedesk before 1.7.57 allows chat template injection.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Usedesk before version 1.7.57 is vulnerable to chat template injection, where malicious input in chat templates can be processed by the template engine without proper sanitization. This could allow attackers to inject arbitrary template code, potentially leading to cross-site scripting (XSS) or server-side code execution.

MitigationUpgrade Usedesk to version 1.7.57 or later to obtain the patch. Additionally, implement input validation and output encoding for all user-supplied data in chat templates as a defense-in-depth measure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine your Usedesk version
    Access your Usedesk installation and locate the version information, typically found in the admin panel under system settings, about page, or by checking the software documentation for version lookup methods.
    Affected if The installed version is any version before 1.7.57 (for example, 1.7.50, 1.7.0, or 1.6.x)
  2. Confirm chat templates feature is active
    Check whether your Usedesk instance has chat templates enabled or configured. Look for chat/template settings in the admin interface or configuration files related to the chat module.
    Affected if Chat templates are actively used or configured in your environment
  3. Examine chat template configurations for user input
    Review the chat template settings where administrators create or modify templates. Inspect template fields that accept dynamic input, such as placeholders for user names, messages, or custom content.
    Affected if Chat templates accept user-supplied data without visible sanitization or encoding controls
  4. Test template rendering behavior
    If you have access to a test environment, create a chat template containing special characters or template syntax (such as {{, }}, <script>, or system command patterns) and observe how the system processes and displays this input.
    Affected if The template engine renders unsanitized input directly, displaying raw template syntax or executing injected code

You are affected if your Usedesk version is below 1.7.57 and chat templates that accept user input are in use, as the template engine will process malicious input without sanitization.
